Definitions

  • the spandex is formed from a polyurethane polymer that has dispersed within the polymer an effective amount of a particles of a mineral mixture of huntite and hydromagnesite.
  • the particles of the mineral mixture are effective in decreasing the as-spun tackiness of the spandex (e.g., typically by at least 50%) and increasing the resistance of the spandex to chlorine-induced degradation (e.g., typically by at least 25%) as compared to the same spandex having no chlorine-resist or anti-tackiness agent present in the spandex.
  • d(50) a median size that is smaller than 10 microns (1 x 10 -5 m), preferably, smaller than 5 microns (5 x 10 -6 m) and most preferably in the range of 1 to 4 microns (1 to 4 x 10 -6 m).
  • d(50) median size
  • the milled particles of all the minerals to be added to the spandex have a median particle size of less than 1 micron (1 x 10 -6 m), preferably less than 0.7 micron (7 x 10 -7 m).
  • Such milling breaks up agglomerates and aggregates and decreases the median size of the particles.
  • Dispersing agents often are used during the milling. After milling, the flow of concentrated slurry is carefully metered into the polyurethane solution to provide the required concentration of additives in the dry spun spandex (e.g., a huntite/hydromagnesite additive concentration in the range of 1.5-5% based on weight of the total weight of the spandex to be dry spun).
  • This example illustrates the surprisingly large decrease in tackiness that is achieved when an effective amount of particles of a mineral mixture of huntite and hydromagnesite is dispersed within the polyurethane of a spandex in accordance with the invention.
  • the tackiness is determined from average over-end take-off tension ("OET") measurements on wound up spandex yarn packages.
  • OET average over-end take-off tension

Abstract

Un spandex comportant des particules d'un mélange minéral de huntite et d'hydromagnésite en dispersion présente un pouvoir collant diminué, une résistance accrue à la dégradation par le chlore, une continuité de fabrication satisfaisante et une faible extraction du mélange minéral lors des opérations typiques de décapage et de teinture acides. Les particules ne donnent pas un pouvoir abrasif excessif et sont acceptables du point de vue environnemental dans les courants effluents.

Claims (6)

  1. Filament ou fibre de spandex dans laquelle la substance formant la fibre est un polymère synthétique à longue chaíne composé d'au moins 85% en poids d'un polyuréthanne segmenté contenant des particules d'un mélange minéral de huntite et d'hydromagnésite dispersé dans le spandex dans une quantité efficace pour diminuer le degré d'adhérence et augmenter la résistance au chlore du spandex.
  2. Spandex selon la revendication 1 dans lequel les particules du mélange minéral sont présentes dans une concentration dans l'intervalle de 1,5 à 5% en poids du spandex.
  3. Spandex selon la revendication 2 dans lequel la concentration des particules du mélange minéral est dans l'intervalle de 2 à 4% en poids du spandex.
  4. Spandex selon la revendication 1, 2 ou 3 dans lequel la huntite constitue au moins 35% en poids du mélange minéral de huntite et d'hydromagnésite.
  5. Spandex selon la revendication 4 dans lequel la huntite du mélange minéral se monte à au moins 95% en poids du mélange minéral.
  6. Procédé pour le filage à sec d'un filament ou fibre de spandex dans lequel la substance formant la fibre est un polymère synthétique à longue chaíne composé d'au moins 85% en poids d'un polyuréthanne segmenté provenant d'une solution d'un polymère de polyuréthanne dans un solvant pour le polyuréthanne, dans lequel le procédé comprend
    la formation d'une émulsion concentrée d'un mélange minéral de particules de huntite et d'hydromagnésite dans un solvant, et facultativement d'autres additifs particulaires et non particulaires classiques, les particules se montant à 10 à 40% du poids total de l'émulsion et le pourcentage en poids de la huntite dans le mélange de huntite/hydromagnésite étant au moins de 35%,
    le broyage de l'émulsion concentrée pour casser les agrégats et les agglomérats des particules et pour diminuer la taille moyenne des particules à moins de 1 µm, et
    l'incorporation de l'émulsion concentrée dans une solution de polyuréthanne dans une quantité suffisante pour fournir une concentration de particules de huntite/hydromagnésite se montant à 1,5 à 5% du poids des filaments à filer, et
    le filage à sec de la solution en filaments.
